Powerful speaking Reviews & Product Details

In a world filled with constant noise, commanding attention when you speak is a rare and invaluable skill. "Powerful Speaking," created by world-renowned sound expert and five-time TED speaker Julian Treasure, offers a transformative masterclass designed to help you find and project your true voice. Whether you are delivering high-stakes corporate presentations, leading team meetings, lecturing in a classroom, or simply wishing to communicate more effectively in your personal relationships, this course provides the tools to ensure your message is not just heard, but deeply felt and remembered. Throughout this engaging curriculum, Julian guides you through the mechanics of vocal production, showing you how to treat your voice as an instrument. You will explore critical concepts such as the "seven deadly sins of speaking"—including gossip, judging, and dogmatism—and learn how to replace them with the four powerful cornerstones of constructive speech: honesty, authenticity, integrity, and love. Additionally, the course delves deep into the practical application of vocal parameters such as register, timbre, prosody, pace, pitch, silence, and volume. By mastering these variables, you will learn to adapt your speaking style to various professional and social contexts, ensuring you project confidence, warmth, and authority in any environment.

Best For

Professionals who want to build greater authority and presence during presentations or meetings. Individuals seeking to improve their vocal resonance, clarity, and overall delivery style. Leaders and managers aiming to foster deeper trust and connection with their teams through better communication. Speakers or educators who want to master the mechanics of voice and body language for maximum impact.

Not For

People looking for a beginner-level public speaking course focused primarily on overcoming stage fright. Learners seeking a highly technical course on vocal anatomy or professional voice acting for animation/gaming. Those who prefer a generic speech-writing curriculum rather than a deep dive into vocal delivery and communication philosophy.
